Castiel watched as Hiccup called Toothless over with a whistle and flew up before circling around to drift next to her holding out his hand for her. She didn't really understand why she would need to ride on Toothless with him for him to show her Berk when she had Aurora she could ride on, but Castiel also really liked the idea of being so close to hi during a flight. With a smile, she nodded and took his hand to climb up onto Toothless's back with Hiccup. She laughed silently and hugged onto Hiccup so she didn't fall off as Toothless took off with fast spins and turns, Aurora following them a little ways behind, though being sure to not interfere. She could defiantly see what Hiccup and Toothless were doing here and she was happy about the idea of her rider finally finding someone. 

Though soon all the spinning an loops stopped and they were high in the air, higher than they had flown since her injuries, and it was a beautiful sight. She looked around in awe and smiled, content to staying up in the sky like this a long a she could.
